I cut my finger pretty badly about two months ago. I didn't go to a doctor because I don't like to and also because I didn't realize how badly it was cut at the time. In any event, it should have healed by now. It was a clean cut across the inside of the right middle knuckle that went to the bone. It has healed to some extent, but I was checking it earlier and found that when I tried to bend it very far the scar turned bright red as if blood was welling just beneath the skin. What in the heck is wrong?
